Setting up a character to walk and talk is the last stage before the process of character animation can begin. This stage is called ‘Character Rigging’ and is the underlying system that drives the movement of a character to bring it to life. This paper will examine several key techniques used in character rigging and provide an explanation of why these procedures are critical to good animation.
